ARK Invest's director of research this week pushed back against a16z crypto's thesis that traditional finance will adopt permissioned blockchain infrastructure instead of decentralized finance. The researcher argued that institutions will increasingly rely on DeFi rails, not permissioned chains.
The core disagreement
A16z crypto has put forward a thesis that traditional financial institutions, facing regulatory pressure and a need for control, will gravitate toward permissioned blockchain networks. These networks restrict who can participate and validate transactions, offering a middle ground between public blockchains and legacy systems.
ARK's director of research disputed that view. In a statement that circulated among industry watchers this week, the ARK researcher argued that institutions will instead lean on DeFi rails — the open, permissionless protocols that power lending, trading, and other financial services on public blockchains.
Why DeFi over permissioned?
The ARK side contends that DeFi's transparency, composability, and global liquidity are too valuable for institutions to ignore. Permissioned chains, by contrast, may sacrifice the very features that make blockchain useful: open access and trust-minimized settlement.
The disagreement isn't academic. It touches on how billions of dollars in institutional capital might flow into crypto over the next few years. If a16z is right, we'll see a wave of private, regulated blockchain networks. If ARK is right, the same institutions will plug directly into existing DeFi protocols.
A split in crypto investment thinking
The public clash between two of the most influential crypto investment firms highlights a growing divide. a16z has long been a major backer of both DeFi and infrastructure projects, but its thesis suggests a pragmatic view of how regulated entities will actually adopt the technology. ARK, known for its bullish stance on disruptive innovation, appears to bet that DeFi's permissionless model will prove irresistible even to cautious institutions.
Neither side has released detailed data or reports backing their positions. The debate, for now, remains at the level of strategic conviction.
Both firms are likely to expand on their arguments in upcoming research notes or public appearances. The crypto industry will be watching for any signs of which direction institutional money actually moves. For now, the question remains open: permissioned or permissionless?
